Install a DIMM
Use this information to install a DIMM.
“
Power off
the server
for this task”
on page
Ground package before opening”
Attention:
• Disconnect all power cords for this task.
• DIMMs are sensitive to static discharge and require special handling. In addition to the standard
guidelines for “Handling static-sensitive devices” on page 29:
– Always wear an electrostatic-discharge strap when removing or installing DIMMs. Electrostatic-
discharge gloves can also be used.
– Never hold two or more DIMMs together so that they touch. Do not stack DIMMs directly on top of
each other during storage.
– Never touch the gold DIMM connector contacts or allow these contacts to touch the outside of the
DIMM connector housing.
– Handle DIMMs with care: never bend, twist, or drop a DIMM.
